Abstract: A light collimation device, a backlight module and a display panel are provided. The light collimation device includes a lampshade and a light guiding part, wherein the lampshade includes a plurality of curved reflecting parts, a first total reflecting part and a second total reflecting part. The curved reflecting part is configured to reflect part of light from a light source arranged at a focal point of curved reflecting part to the first total reflecting part. The first total reflecting part is configured to reflect part of incident light to the second total reflecting part and directly direct another part of light to the light guiding part. The second total reflecting part is configured to reflect incident light to the light guiding part. The light guiding part is configured to cause incident light to propagate in a total reflection.

Abstract: A display panel, a display device and a display method. The display panel includes a first microlens array, a pixel island array and a second lens. The pixel island array is configured to display a plurality of sub-original images. The first microlens array is configured to converge light emitted from the plurality of sub-original images so as to obtain imaging light, and the imaging light is capable of forming a first virtual image. The second lens is on a user viewing side of the display panel relative to the first microlens array, and the second lens is configured to converge the imaging light so as to obtain a second virtual image. The first virtual image is a virtual image in which the plurality of sub-original images are stitched and enlarged, and the second virtual image is an enlarged virtual image of the first virtual image.

Abstract: A head-up display device, a method for controlling the same, and a vehicle are provided. The head-up display device includes a display component, a first optical component, a second optical component, and a synthesizing component. The light in different polarization directions or states can be transmitted or reflected by the first optical component, so that state information projection light and augmented reality information projection light can be separated from each other to thereby be dual-layer displayed. For example, augmented reality information can be displayed at a longer distance from eyes of a driver so that the focus of the human eyes does not need to be adjusted frequently to thereby make it comforter to view the information so as to eliminate a hidden risk.
